Cannot commit delete row from VO

I have a VO that I have no problem create new row, update existing row and commit. But I can't commit deleted row to database. no exception or error message etc... and All other VOs are working fine,
anybody has any idea why? is that an option or something on VO? or is it an BC4J bug?
Thanks,
-Ming

You are in the wrong forum. Try your question JDeveloper and ADF .
And please consider this too (copied from this thread Concerned in delayed response
a) Use a good subject line that briefly describes the issue. This will attract those familiar with that area to come and help.
b) Tell us what database version you are using. Not just saying e.g. "10g" but more specifically "10.2.0.3"
c) Describe the issue clearly stating what you have tried, and what you are trying to achieve.
d) Don't use txt spk because this is a professional forum, not a chat room and not everyone can follow it.
e) Don't USE CAPITAL LETTERS IN YOUR DESCRIPTION as this is considered shouting and agressive.
f) Provide sample data for us to use if necessary either with the CREATE TABLE and INSERT statements to create it or providing a WITH clause that we can use. This saves us from having to type in and format the sample data for ourselves and is more likely to attract us to help.
g) Show the code that you have already tried (if you haven't tried any code yet then why not? have a go yourself and only ask for help when you get stuck).
h) Show us any error messages you are getting, in full, and with information of the line numbers where the error is occurring
i) Wherever you provide data or code remember to use the tag before and after or the [code] tag before and the [/code] tag after, so that it keeps it's layout and is clear to read.
j) Perhaps one of the most important things of all... never suggest that you need a solution "urgently" or that your issue is "urgent". This implies that your issue is somehow more important than the issues posted by other people. Everybody would like an answer to their issue promptly, but it just depends when people are online who can answer the question and nobody is being paid to answer it, so it is arrogant and rude to demand urgent attention to your own. If something is that urgent then you should raise it through oracle metalink as a priority issue or pay for someone with the necessary skills to come and do the work for you.

Cannot DELETE rows from LOV on running...is it a bug ??

One of the features I appreciated in the new version of JHeadstart is that we can now insert, modify and delete rows on LOV (even in the database).
We have just to check on Lookup properties :
Multi-row insert allowed
Multi-row update allowed
Multi-row delete allowed
I cheked all of them and on runnig I could insert and update records in LOV.
When I tried to delete records from LOV the system display information message "nothing to save" and in fact no records were deleted.
Normally since I checked the delete property it should be possible to delete rows from LOV
thanks for any Help

Monta,
I could reproduce this, it is a bug. Added to the fix list for the next release.
Thanks for reporting,

How can I implement the equivilent of a temporary table with "on commit delete rows"?

hi,
I have triggers on several tables. During a transaction, I need to gather information from all of them, and once one of the triggers has all the information, it creates some data. I Can't rely on the order of the triggers.
In Oracle and DB2, I'm using temporary tables with "ON COMMIT DELETE ROWS" to gather the information - They fit perfectly to the situation since I don't want any information to be passed between different transactions.
In SQL Server, there are local temporary tables and global. Local temp tables don't work for me since apparently they get deleted at the end of the trigger. Global tables keep the data between transactions.
I could use global tables and add some field that identifies the transaction, and in each access to these tables join by this field, but didn't find how to get some unique identifier for the transaction. @@SPID is the session, and sys.dm_tran_current_transaction
is not accessible by the user I'm supposed to work with.
Also with global tables, I can't just wipe data when "operation is done" since at the triggers level I cannot identify when the operation was done, transaction was committed and no other triggers are expected to fire.
Any idea which construct I could use to acheive the above - passing information between different triggers in the same transaction, while keeping the data visible to the current transaction?
(I saw similar questions but didn't see an adequate answer, sorry if posting something that was already asked).
Thanks!

This is the scenario: If changes (CRUD) happen to both TableA and TableB, then log some info to TableC. Logic looks something like this:
Create Trigger TableA_C After Insert on TableA {
If info in temp tables available from TableB
        Write info to TableC
   else
       Write to temp tables info from TableA
Create Trigger TableB_C After Insert on TableB {
If info in temp tables available from TableA
        Write info to TableC
   else
       Write to temp tables info from TableB
So each trigger needs info from the other table, and once everything is available, info to TableC is written. Info is only from the current transaction.
Order of the triggers is not defined. Also there's no gurantee that both triggers would fire - changes can happen only to TableA / B and in that case I don't want to write anything to TableC.
The part that gets and sets info to temp table is implemented as temp tables with "on commit delete rows" in DB2 / Oracle.
What do you think? As I've mentioned, I could use global temp tables with a field that would identify the transaction, but didn't find something like that in SQL Server. And, the lifespan of local temp tables is too short.

Oracle deleting rows from tables starting with the name PQ

hai friends
we are given access rights to delete only tables starting with PQ. HAVING PQ_NUM as primary key for all the PQ tables.
totally we have 6 tables. PQ_01,PQ_02, PQ_03,PQ_04,PQ_05,PQ_06.
ALL This tables will have one primary key. for example pq_01 willl have pq01_num as primarykey and pq_02 table will have pq02_num as primary
key.
pq01_num value will exist in all the primary key of pq tables.
i want query to delete rows from the pq tables based on the input value i give.
for example if i give primarykey value 122 then that value in pq tables should be deleted.
One more problem is there. pq_06 table does not have pq02_num column. here the column differs. it is pq06_num_req.
so give your idea of deleting the rows from pq tables
waiting

I dont have access to databse,this is untested
declare
v_cmd varchar2(2000);
columnname varchar2(30);
input_value number:=??;
tabowner varchar2(30):=???
begin

Cannot fetch a row from OLE DB provider "BULK" with bulk insert task

Hi, folks:
I created a simple SSIS package. On the Control Flow, I created a Bulk INsert Task with Destination connection to a the local SQL server, a csv file from a local folder, specify comma delimiter. Then I excute the task and I got this long error message.
[Bulk Insert Task] Error: An error occurred with the following error message: "Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.The bulk load failed. The column is too long in the data file for row 1, column 1. Verify that the field terminator and row terminator are specified correctly.".

I got the same error with some additional error details (below). All I had to do to fix the problem was set the Timeout property for the SQL Server Destination = 0
I was using the following components:

Unable to delete rows from Target.

Hello everyone,
I am unable to delete rows from target data store. Here is what I have done.
Source Oracle 10g - staging 11g - Target Oracle 11g
I have implemented consistent set CDC on data model in staging and added 2 tables to CDC and turned on the journals . Both tables A and B are joined together via Column E (primary key of table A). Table A is the master table(has foreign key). Table B is child table. Target column consists of all the columns of both table A and B.
Following is what I am able to do and not to do
ABLE TO DO. If data is inserted into both or any of journalized tables I can successfully load the same in target by performing following steps. 1. Extend the consistency window at model level. Lock subscriber. Run the interface with any source table marked as Journalized data only. Unlock subscriber and purge journal.
ABLE TO DO. If data is updated in any of the journalized table, along with the steps mentioned above I can execute two interfaces. In one Interface table A marked as journalized data only Joined with table B and in second interface table B marked as Journalized data only joined to table a.
NOT ABLE TO DO If data is deleted from one or both tables it shows up as journalized data in JV$D<tablename> marked as D with date and subscriber name but when i run the interface by extending the window , locking subscriber executing both interfaces, unlock subscriber purge journals. no change takes place is Target. After unlocking subscriber step, journalized data gets removed from JV$D view. Please let me know what I am doing wrong here. How can rows delted from source can also be deleted from TARGET?
NOTE : In the flow table SYNC_JRNL_DELETES is YES
In moel under jounalized table tab Table have following order Table A folloed by Table B
Thanks in advance

Sorry I still do not get it. when you say "Its a legacy app", are you talking about the VB.NET app ?
If so then I repeat my self :-) Why not to connecting to the SQL server directly?
* even if you need information from several databases (for example ACCESS + SQL Server), in most cases, it is much better to connect directly and get each information to the app. Then in your app you can combine the information and analyse it

Access app is the legacy app.

Deleting rows from a table

COuld anyone tell me how to delete rows from a table which has millions of rows.
TIA,
Oracle user

if you are deleting all the rows, use "truncate table" in sql*plus.
or if you are deleting all but a handful of rows, then copy the rows you still want to a spare table, drop the original table, and rename the spare table back to the original table's name.
hope this helps

Problem "The OLE DB provider for linked server reported an error. The provider reported an unexpected catastrophic failure Cannot fetch a row from OLE DB provider for linked server"

hi
i'd like to ask question about linked server.
my linked server used to work but now when i try to select from linked server i was told "The OLE DB provider for linked server reported an error. The provider reported an unexpected catastrophic failure Cannot fetch a row from OLE DB provider
for linked server"
but in fact for test connection i was told "the test connection to the linked server succeeded".
could anyone help me? thank u very much
best regards
martin

Hi,
In addition to Tracy's post we have to know those answers as well:
* what provider are you using for the connection
* what do you connect to
for example, if someone try to connect to oracle using sql server provider then several simple queries are going to work probably OK, but once you are trying to use T-SQL or any complex SQL query then the errors are starting.
please post the connection string (without the password!) + the query that you are trying to use.

Delete rows from table...Bizarre problem.

Folks
i HAVE this bizarre problem.
I hava a Java class which displays data read into a table with a delete
option by the side of each row.
Now lets assume you have 3 rows in the Table.
abc deleteButton
efg deleteButton
xyz deleteButton
When I click the first delete,that row gets deleted from the table.(perfect...)
Now I have 2 rows.
When I click on the first row,I get the error
'You clicked -1'
java.lang.ArrayIndexOutofBoundsException: -1 < 0.
Can anyone tell me why this is happening even though there are rows in the table.???
ActionListener al = new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("You clicked row : " + table.getSelectedRow());
javax.swing.table.TableModel model = table.getModel();
Object o = model.getValueAt(table.getSelectedRow(),0);
//System.out.print(model.getValueAt(table.getSelectedRow(), 0));
//System.out.println();
MyDeleteFunction(o.toString());
// Delete row from window.
((DefaultTableModel)table.getModel()).removeRow(table.getSelectedRow());
table.revalidate();
table.repaint();

Delete rows from Tabular form

Hi,
Anyone knows how dynamicly delete rows from Tabular Form (on button click, button is as item)?
Thanks.

I am in a great fix. We had a test instance.. and we had a version apex 3.2.. But when the same application has been uploaded to prod.. we used apex 4.0.Why on Earth would you do this? The whole point of the testing is to verify that the application will work in the production environment: the first requirement for this is that the test and production environments are equivalent.
has any body is facing the same issue as mine..Yes, as is easily discovered by searching the forum...see Delete button doesn't work in tabular form after upgrade from APEX3.2 to 4.

within one row i have one field containing the status and i want to be able to select the status from a combo/dropdown-field and set it for this particular row.
thanks in advance!

Hi,
Report BCALV_EDIT_04 shows how to append and delete rows.

Deleting rows from a JTable

Hello,
I've got a JTable which is based on a 2-dimensional array, which contains my data. Now I want to delete several rows from the JTable. There's the possibility to modify my data-array by creating a new array which doesn't contain anymore the datasets I want to delete. Afterwards I can redraw the table and my rows are deleted. But I think that's a very complicated way to delete rows from a JTable. Can anybody tell me whether ther's an easier way to do so ? I'd really be pleased...
Thanx,
Findus

When you create a TableModel using a two-dimensional array or a Vector of Vectors, a DefaultTableModel is created and it stores the data in its own Vector of Vectors. The DefaultTableModel supports methods for adding/removing rows of data. To remove the first row in the table you would do something like:
DefaultTableModel model = (DefaultTableModel)table.getModel();
model.removeRow( 0 );
Note: once you create the TableModel you should set your array to null as it is not used anymore.

Deleting rows from very large table

Hello,
I need to delete rows from a large table, but not all of them, so I can't use truncate. The delete condition is based on one column, something like this:
delete from very_large_table where col1=100;
There's an index (valid, B-tree) on col1, but it still goes very slow. Is there any instruction which can help delete rows faster?
Txh in adv.
A.

Your manager doesn't agree to your running an EXPLAIN PLAN? What is his objection? Sounds like the prototypical 'pointy-hair boss'.
Take a look at these:
-- do_explain.sql
spool explain.txt
-- do EXPLAIN PLAN on target queries with current index definitions
truncate table plan_table
set echo on
explain plan for
<insert query here>
set echo off
@get_explain.sql
-- get_explain.sql
set linesize 120
set pagesize 70
column operation     format a25
column query_plan     format a35
column options          format a15
column object_name     format a20
column order           format a12
column opt           format a6
select     lpad(' ',level) || operation "OPERATION",
     options "OPTIONS",
     decode(to_char(id),'0','COST = ' || NVL(to_char(position),'n/a'),object_name) "OBJECT NAME",
     cardinality "rows",
     substr(optimizer,1,6) "OPT"
from     plan_table
start     with id = 0
connect by prior id = parent_id
There are probably newer, better ways, but this should work with all living versions of Oracle and is something I've had in my back pocket for several years now. It's not actually executing the query or dml in question, just running an explain plan on it.
